Air & Water Reactions

Pyrophoric in air [Hawley]. Reacts violently with water, Rose(1961).

Reactivity Profile

Organometallics, such as DIETHYLALUMINUM CHLORIDE, are reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents. Often reactive with water to generate toxic or flammable gases. Organometallics containing halogens (fluorine, chlorine, bromine, iodine) bonded to the metal typically with generate gaseous hydrohalic acids (HF, HCl, HBr, HI) with water.

Purification Methods

Distil it from excess dry NaCl (to remove ethyl aluminium dichloride) in a 50-cm column containing a heated nichrome spiral. [Beilstein 4 IV 4403.]

METHOD FOR MANUFACTURING DIALKYL ZINC AND DIALKYL ALUMINUM MONOHALIDE

Disclosed is a manufacturing method for dialkyl zinc and dialkyl aluminum monohalide that makes it possible to efficiently manufacture both dialkyl zinc and dialkyl aluminum monohalide of high purity and at a high yield on an industrial scale with a single reaction from zinc chloride and trialkyl aluminum starting materials, while suppressing the production of precipitates in the reaction process and suppressing the adhesion of precipitates to the equipment and the admixture thereof into the product. The manufacturing method for dialkyl zinc and dialkyl aluminum monohalide is a dialkyl zinc and dialkyl aluminum monohalide manufacturing method that causes a reaction between zinc chloride and trialkyl aluminum, and uses trialkyl aluminum with a hydride concentration of 0.01 mass% to 0.10 mass%. Dialkyl zinc that contains essentially no aluminum is separated from the reactants, and then dialkyl aluminum monohalide that contains essentially no zinc is separated.

PROCESS FOR PRODUCTION OF ALUMINUM DIALKYL MONOHALIDE

A method for manufacturing dialkylaluminum monohalide is provided by which dialkylaluminum monohalide substantially including no zinc component after recovering dialkylzinc from a reaction product obtained by a reaction of zinc halide and trialkylaluminum used as raw materials can be efficiently obtained on an industrial scale at a high yield. According to the method for manufacturing dialkylaluminum monohalide of the present invention, zinc halide is reacted with trialkylaluminum to produce dialkylzinc and dialkylaluminum monohalide, and after the dialkylzinc is separated from a reaction product by distillation, metal aluminum in which a molar ratio is 0.40 or more to zinc component, that is dissolved in the reaction product, and then the mixture is distilled to separate the dialkylaluminum monohalide which substantially includes no zinc component.

Stereoselective olefin polymerization catalysts generated by the transfer-epimetalation of olefins or acetylenes with dialkyltitanium(IV) complexes: Three-membered metallocycles as proposed chiral sites

Efficient transfer-epimetalations of simple olefins and acetylenes by R2TiL2 reagents (R = Bun, But; L = X) are readily achieved in THF at -78°C to generate titanacyclopropa(e)ne intermediates, readily capable o

CINDP study of the Ni(acac)2-catalyzed reaction of triethylaluminum with chloroform

CIDNP effects were found in the Ni(acac)2-catalyzed reaction of Et3Al with CHCl3. The effects appear in the products of transformation of the diffusion radical pair of the ethyl and dichloromethyl radicals. The radical route is a side process in this reaction, and the main products, Et2AlCl, ethane, and ethylene, are formed by a nonradical route. A general mechanism of the reactions of Et3Al with CHCl3 and CCl4 including radical and ion-coordination processes was suggested.

Titanium-catalyzed cyclotrimerization of butadiene. Part II. The (C6H6)TiII(AlCl4)2-EtxAlCl3-x (x=1-3) systems

This paper describes the kinetics of butadiene cyclotrimerization catalyzed by the Ia-EtAlCl2, Et2AlCl or Et3Al systems and the results of investigations of these systems by electronic absorption spectroscopy. The study was carried out to improve understanding of the effects of organo-aluminum compounds on the catalytic properties of Ia and to find the optimum conditions for (Z,E,E)-CDT production. In view of our long-term efforts to identify the catalytic species in the butadiene cyclotrimerization in systems based on different titanium precursors, this is the initial step in a comparative study of the (arene)titanium (II) systems and the Ti(IV)-based systems.

Bis- and Tris-aluminum-alkane Compounds as Intermediates During the Dissolution of Aluminum Metal with Olefins in the Presence of Aluminum Trichloride or Alkyl Aluminum Dichloride

Aluminum can be dissolved by ethylene in the presence of aluminum trichloride to form primarily bis-(dichloro-aluminum)-ethanes (1) and (2) or in the presence of ethyl aluminum dichloride to form chloro-aluminum-ethyl-(dichloroaluminum)-ethane (3) and/or a tris-aluminum compound Cl2Al-C2H4-Al(Cl)-C2H4-Al(Cl)Et (4). 1-4 reacts further with olefins, with elimination of alkyl aluminum dichloride and/or dialkyl aluminum chloride, which are practically inert towards olefins.The C2H4-bridge is available to the growth and displacement reaction with olefins. - Keywords: Bis- and Tris-aluminum-alkane Compounds, Aluminum

Process for the simultaneous manufacture of dimethylaluminum chloride and alkylaluminum chlorides

A redistribution process for the simultaneous production of dimethylaluminum chloride and numerous alkylaluminum chlorides is described herein. The redistribution process is a chemical reaction which consists of first forming a mixture of methylaluminum dichloride and at least one alkylaluminum compound selected from the group consisting of an aluminum trialkyl, a dialkylaluminum chloride, and an alkylaluminum sesquichloride, where "alkyl" refers to a group containing 2 to 16 carbon atoms. The relative amounts of the mixture components are fixed such that the mixture has a chlorine-to-aluminum atomic ratio of 1.0 to 2.0. The mixture thus formed is next subjected to a fractional distillation, in which a first fraction is obtained, consisting of dimethylaluminum chloride, essentially free of trimethylaluminum, methylaluminum dichloride, and other impurities. The distillation residue consists essentially of alkylaluminum chlorides, which are valuable commercial materials. Dimethylaluminum chloride itself is useful as a methylating agent, a polymerization cocatalyst, a chemical intermediate, and a pyrophoric fuel.
